Kutheni le nto intsebenzo yokutywina ye-valves itshintsha ivila?

Kutheni intsebenzo yokutywinaI-valves yebholaNgaba uyahluka kuguquko lobushushu?

Njengoko icandelo eliphambili lokulawula imibhobho yemizi-mveliso, ukusebenza kokutywina kweeVenkile zebhola kuchaphazela ngqo ukhuseleko kunye nokuthembeka kwenkqubo. Nangona kunjalo, kwizicelo ezisebenzayo, iziphumo zokutywina kweevali zebhola zihlala zahluka kakhulu ngenxa yokuguquguquka kweqondo lobushushu, olunxulumene ngokusondeleyo kwiimpawu, uyilo lwesakhiwo, kunye nokuziqhelanisa neemeko zomsebenzi.

1. Umahluko kwi-thermal yokwandiswa kwezinto zokutywina

Ubume bokutywinaI-valves yebholaidla ngokudityaniswa kwezitulo ze-valve zentsimbi kunye nezixhobo ezithambileyo zokutywina (ezinje nge-ptfe, i-nylon) okanye amatywina anzima. Xa amaqondo amaqondo amaqondo anyukayo, i-coefficients eyahlukileyo yokwandiswa kwe-thermal yezinto ezahlukeneyo kunokukhokelela kutshintsho kumsali ofanelekileyo. Umzekelo, amakhonkco okutywina ePute anokutsala amaqondo obushushu asezantsi, onokubangela ukuvuza; Ukwanda kokugqithisa kubushushu obuphezulu kunokuwanyanzela ukunxiba kwaye kubengele ukuba ibhola ibambeke. Nangona i-valves eqinileyo etywiniweyo inokumelana nobushushu obuphakathi, umahluko kwingxaki ye-vall yentsimbi kwaye ibhola isenokukhokelela ekunciphiseni komgangatho wokutywina, ukwenza amajelo okuvuza amancinci.

2. Impembelelo yeqondo lobushushu kwimithombo yeendaba

Utshintsho lobushushu lunokutshintsha imeko yendawo, enjengokufakwa kunye nesigaba, ngaloo ndlela ichaphazela ukusebenza kwebhola. Phantsi kweemeko zobushushu eziphantsi, i-medium inokufuna okanye ikhuphe i-crystaillize, ivimba umphezulu wokutywina; Amaqondo obushushu aphezulu anciphisa ubunzima bezixhobo zokutywina kunye nokukhawulezisa ukwaluphala. Umzekelo, kwiinkqubo ze-Steam, uSteam-Herey Steam unokwenza amatywina e-PTFE, ngelixa ukungcola kumanzi acociweyo kunokukrola umhlaba wokutywina, kubangela ukuvuza kweevali zeValve ngexesha lokuvula nokuvalwa.

I-3. Ukulungelelaniswa okungapheliyo kuYilo loSakhiwo

Ezinye uyilo lwevali zebhola bezingakhange ziqwalasele ngokupheleleyo iindlela zembuyekezo zobushushu. Umzekelo, ukuba isihlalo senkxaso yevalve ye-valve ye-valve yebhola esiyishiyayo, ayinakulungelelanisa ngokuzenzekelayo umlinganiso wokutywina xa iqondo lobushushu litshintsha, libangela ukungaphumeleli. Nangona i-valve edadayo inokuthi ihlawule amandla okutywina ngokuhamba kwebhola, uxinzelelo olusebenzayo kwiqondo lobushushu eliphezulu kunokubangela ukufuduka kwebhola, enokonakalisa itywina. Ukongeza, ivali yebhola exhumelwe li-welding zithambekele kwingxaki ngenxa yoxinzelelo loxinzelelo lwe-thermal kumaqondo obushushu aphezulu, enza ngaphezulu komngcipheko wokuvuza.

Isisombululo: Kwiimeko eziphezulu zokusebenza, inyibilikisi etywiniweyoI-valves yebholaInokukhethwa kwaye iveli yesihlalo sesihlalo sasentwasahlobo inokukhetha; Imeko yobushushu ephantsi ifuna ukusetyenziswa kwezinto ze-anti brittle (ezinjengee-peek) kunye nokwanda komhlaba wokutywina. Kwangelo xesha, kuhlolwa rhoqo intsebenzo yokutywina kweeVenkile zeBhola yePhazulu kunye nokulungelelanisa imijikelezo yesondlo ngokusekwe kwi-CORCES CORVES CORVESS ukuze kwandise izixhobo zokusebenza ngokufanelekileyo.
